When is a car even more nebulous than a concept? When it's a "design study". The McLaren P1 ($TBA) is a perfect example. While the design of the final product is sure to be close to what we're viewing here — and that's certainly a good thing — the specs are shrouded in mystery. All we're promised is "the best driver's car in the world on the road and track", which we hope is good enough for anyone ponying up the cash for this beast when it goes on sale in the next year.
